SB5101 Cable Modem Overview
1 Introduction
The SB5101 Cable Modem is a stand-alone unit with an external power supply, it is the latest
product in the Motorola Surfboard range, the SB5101 will be produced alongside the existing
SB5100 modem and will eventually replace it.
Figure 1: SB5101 Cable Modem
The SB5101 offers both Ethernet and USB interface connectivity to ensure compatibility with
almost any PC or Macintosh network-ready computer system. The SB5101 Cable Modem received
DOCSIS 2.0 certification in Cable Labs Certification wave 28 (April 2004). The SB5101E
EuroDOCSIS Cable Modem received the corresponding EuroDOCSIS 2.0 certification in ECW 16
in September 2004.
A top panel standby switch has been added for additional end-user security. It disconnects the
USB and Ethernet connection to the CPE without disconnecting the cable modem from the RF
network; providing a simple but effective reassurance for the customer that their PC is safe from
unwanted external access.

SB5101 Cable Modem Overview
3 SB5101 Benefits for the MSO and End User
3.1
Connectivity
The USB port is an important interface for MSOs because it can dramatically reduce their
installation time and installation cost. The USB interface was introduced in most PCs starting in
1997. Practically all PCs from 1998 onward were sold with a USB interface. The USB interface
allows a user to connect up to 127 devices simultaneously without ever having to open their PC.
The MSO saves time by not having to open a PC to install an Ethernet NIC card to install a cable
modem. In fact, the USB interface simplifies the cable modem installation so much that in many
cases the consumer will be able to self-install the modem, thus making the SB5101 an ideal choice
for retail or self installation. In addition to saving time the consumer and MSO will no longer need
to invest additional funds for a NIC card. Currently Windows 98, Windows 2000 and Windows XP
support the USB interface.
A 10/100BaseT Ethernet interface is also available for those customers who do not have a PC with
an active USB port or wish to continue to use the Ethernet interface, the connections are bridged
so if the MSO allows multiple devices may connect through the Modem simultaneously.
3.2
Standby Switch
The SB5101 series also features a standby switch that temporarily disconnects the modem from
the PC, thus allowing for a greater degree of security when the user is not surfing while keeping
the modem on the network, thus allowing the modem to be monitored, updated, and maintained
by the MSO continuously.
3.3
User Guide
The SB5101 User Guide is available in multiple languages including German, English, French
(including Canadian French), Portuguese (including Brazilian Portuguese), Danish, Swedish,
Korean, Japanese, Simplified and Traditional Chinese, Polish, Dutch and Spanish.
3.4
Modem Set Up and Diagnostics
The SB5101 has an html based web page that will allow an MSO engineer or a customer to easily
troubleshoot any problems with connecting the modem onto the HFC network. In addition there is
a Motorola developed program called Stormwatch which allows a dynamic GUI for both local and
remote access to an individual Cable Modem.
In addition Motorola has developed a Modem Configuration File utility called “Beachcomber” which
is designed to simplify the production and maintenance of the essential config files.
3.5
Logistics
Motorola has invested in a very sophisticated product fulfilment operation based in Scotland which
allows the SB5101 and its accessories to be customised to the needs of individual operators.

SB5101 Cable Modem Overview
4 SB5101 Architecture.
The key physical component portion of the SB5101 system is the BCM3349 chip (Broadcom). The
BCM3349 is a single-chip that supports the two advanced communication technologies required by
the DOCSIS 2.0 specification – advanced time division multiple access (A-TDMA) and
synchronous code division multiple access (S-CDMA). Other parts of the Cable Modem include a
BCM3419 Silicon Tuner, SDRAM, non-volatile storage (Flash), Ethernet interface, and USB
interface. The SB5101 provides 16 Service ID’s (SIDs) rather than the 4 available with the
SB5100, this provides much greater flexibility for the provision of multiple services with individual
QoS, determined by the needs of the service, data, voice, video etc.

SB5101 Cable Modem Overview
5 DOCSIS - Overview
The DOCSIS system was developed to enable hardware and systems
interoperability and automated configuration and management. Cable
Modems (CM’s) and Cable Modem Termination Systems (CMTS’s) from
various vendors will operate on the same network, using the common
DOCSIS standards and protocols. In this model, a CM is authorized by
the CMTS for use on the network, and configures itself according to
parameters that are passed to it from the head-end. This sequence of
events will occur automatically in the background, so the user will be
unaware of the activity. The following paragraph describes the process
of how a CM “logs on” to the network.
When the CM is powered on, it follows one of two scenarios. If it is
logging on to the network for the first time (or the data frequency has
been changed), the CM automatically scans the frequency spectrum to
locate the data frequency. If the CM has previously accessed the
network, it will lock onto the data frequency automatically (the previous
session value is stored). Once the CM finds the DOCSIS data signal, it
looks for a message that contains the basic parameters for the upstream
(frequency, modulation, symbol rate, FEC format, etc.). The CM can
then transmit a message to the CMTS requesting additional information
that will enable it to connect to the network. Through a series of
messages and interactions, the CM will establish IP connectivity using
DHCP, (dynamic addressing), and then will receive a configuration file
via TFTP that has additional parameters the CM needs to configure
itself. Once the CM has been configured, it will register with the CMTS
and be authorized for use of the network. If Baseline Privacy has been
enabled, the final step of the initialization is establishing the parameters
to use Baseline Privacy.
Once the CM has been configured and authorized, it can use the
network like any standard Ethernet network device. The Operations
Support System (OSS) software in the CMTS communicates with all the
CMs and has the ability to re-configure them to use different channels,
to change their parameters, and to disable their ability to use the
network.

6 SB5101 Indicators and their use for diagnostic purposes.
The indicators on the surfboard modem are designed to be helpful to both the end user and the
network operator. The indicators allow an initial diagnosis to be made as to the likely cause of
reported problem. The problems which can be diagnosed divide into the modem itself, the power
light does not go solid green; the HFC network, either the Receive or Send does not go solid
green; the IP network, the Online does not go solid green or finally the user CPE, no activity light.

7 WEB Page Diagnostic Tool.
The Cable Modem has three active interfaces, the HFC, the Ethernet and the USB and each
interface has both a MAC and an IP address associated with it. When operating normally it is the
IP address of the HFC interface that is used for diagnostic access to the modem. However the IP
address associated with the Ethernet interface is always available to the client side network,
unless it has been disabled by management command. This means that a PC on the client side
can access the WEB pages within the modem using the reserved address 192.168.100.1. This is
a non-routed address so it cannot be reached from the Internet (routed) side of the network
The SB5100 family of modems contain an internal DHCP server, which is active until the modem
registers with the CMTS. In the case of a problem that prevents the modem from completing its
registration, the modem can still give an IP address to the client PC to enable diagnostics access.
This address is given with a very short lease (around 10 seconds) so that as soon as the
registration does complete the client PC obtains its proper IP address from the core network
DHCP server.
The WEB interface consists of the following pages:

Stormwatch is a diagnostic tool to monitor and troubleshoot Cable Modems from the CPE or HeadEnd.
Stormwatch provides a real-time visual status of SURFboard Cable Modems it also provides the
status of the standard SNMP objects on any DOCSIS Modem
Stormwatch monitors Cable Modem via SNMP objects
Stormwatch can be CPE or Head-end based
The Stormwatch application allows for one time load, or a permanent installation. It is also
available in two versions one of which is read only and the other is read write. In the read only
version the drop down tags which allow options to be changed do not appear hence there is no
way to modify modem parameters.

9 Modem Profiler - Beachcomber
Beachcomber is a DOCSIS 1.0/1/1/2.0 Cable Modem Configuration file editor which runs on
Windows, Linux and Unix based systems. It features a simple Java based user interface which
includes checking of data fields as they are entered. It is a tool designed to make life easier for
both the experienced operator by automating the configuration process and for the less
experienced operator by providing extensive help facilities.

SB5101 Cable Modem Overview
One aspect of configuration management which needs to be managed carefully is the use of
Filters and Access lists. These tables are used by the operator to determine what services their
customers and use and more importantly to block activities which the operator does not want to
allow.

Page 28 of 34
SB5101 Cable Modem Overview
DOCSIS 1.1 introduced the idea of Service Flows with individual QoS levels so that an operator
can distinguish between the QoS requirements of different types of end user service and allocate
the resources required to ensure the customer actually receives the service they are paying for.
Beachcomber allows the definition of both the upstream and downstream service flows and the
classifiers which determine the admission to those flows, the graphical presentation makes it easy
to see what is being configured and to compare the details of different configurations.

10 Diagnostic Modem
The diagnostic modem is physically the same as a customer modem except that it is orange in
colour, it has a small jack socket on the rear and it has a special “shelled” version of the
microcode. This is a simplified Korn shell system, which allows the user to log onto the device and
set diagnostic switches to trace and log what is happening on the network. This is a very powerful
tool for tracing intermittent and otherwise difficult faults.
10.1
Diagnostic Cable Modem Command Line Interface Notes
The CLI can only be accessed via an “rlogin” based Telnet client or the Diagnostic
Console Cable and the DIAG port on the back of the modem. Modems that are going to be
used as Diagnostic Tools and use the CLI must have the “SHELL” version of modem
firmware.
